OBJECTIVE: To investigate serum creatine kinase (CK) levels in pregnant women with ectopic pregnancy (EP), spontaneous abortion, and normal pregnancy with comparable serum hCG concentrations.
DESIGN: A retrospective, case-controlled study.
SETTING: Helsinki University Central Hospital, Helsinki, Finland.
PATIENTS: Forty-four patients with a suspicion of EP of which 15 had laparoscopically confirmed tubal pregnancies; 15 had a spontaneous abortion, a blighted ovum, or a missed abortion; and 14 patients a normal intrauterine pregnancy.
INTERVENTIONS: The diagnosis was made by transvaginal sonography and serum hCG determinations either at admission or after repeated examinations. Ectopic pregnancy was confirmed and treated by laparoscopy.
MAIN OUTCOME MEASURES: Serum CK and hCG levels.
RESULTS: No significant differences in CK levels were observed between the groups by one-way analysis of variance and no correlation was found between serum CK and hCG levels within any group.
CONCLUSIONS: Creatine kinase does not appear to be useful in the diagnosis of early EP.
